NSE and BSE F&O Average Daily Turnover Plunges to 34-Month Low of ₹1.69 Lakh Crore in September

Trading activity across Indian equity bourses witnessed a sharp contraction in September, with participant engagement waning across both derivatives and spot markets. According to exchange data compiled by Kishor Kadam from the National Stock Exchange (NSE) and BSE, average daily turnover (ADTV) in the futures and options (F&O) segment dropped 7.5% month-on-month to ₹1.69 lakh crore (up to September 25), sliding to its lowest level in 34 months.

The cash segment mirrored this subdued sentiment, with average daily turnover declining 5.1% month-on-month to ₹1.24 lakh crore, marking a seven-month low.

Relentless Decline in Derivative Volumes

The decline in September represents the sixth consecutive month of shrinking activity in equity derivatives. After scaling an annual peak of ₹3,11,622 crore in March, derivative turnover has steadily drifted downward:

Month-Wise F&O Daily Average Turnover:

• January: ₹2,76,209 crore
• February: ₹2,65,462 crore
• March: ₹3,11,622 crore
• April: ₹2,55,423 crore
• May: ₹2,55,048 crore
• June: ₹2,33,038 crore
• July: ₹2,11,154 crore
• August: ₹1,83,076 crore
• September (up to Sep 25): ₹1,69,420 crore

Between March and September, average daily derivative turnover contracted by over 45%, underscoring a pronounced structural shift in how retail and proprietary desks are deploying risk capital.

Cash Segment Touches Seven-Month Low

Activity in the underlying cash market also experienced fatigue following strong trading momentum earlier in the year. While spot market volumes expanded during the spring months to touch an annual high in May, trading interest has since moderated:

Month-Wise Cash Segment Daily Average Turnover:

• January: ₹1,28,613 crore
• February: ₹1,23,339 crore
• March: ₹1,34,544 crore
• April: ₹1,44,032 crore
• May: ₹1,52,233 crore
• June: ₹141,961 crore
• July: ₹1,30,286 crore
• August: ₹1,30,272 crore
• September (up to Sep 25): ₹1,23,578 crore

The September figure of ₹1,23,578 crore represents the lowest cash turnover level since February's ₹1,23,339 crore.

Regulatory Headwinds Reshape Market Dynamics

The persistent cool-off in derivatives activity comes against the backdrop of sustained interventions by the Securities and Exchange Board of India (SEBI) and the Ministry of Finance aimed at curbing retail over-speculation.

A succession of regulatory actions has increased entry barriers and trading costs for retail traders:

Key Drivers of the Derivatives Slowdown:

• Contract Size Rationalisation: Revision of minimum index derivative contract values from ₹5–10 lakh to ₹15–20 lakh, demanding greater margin commitments from retail participants.
• Curbs on Weekly Expiries: Rationalisation limiting each exchange to weekly expiry contracts on just one benchmark index, significantly reducing the cadence of zero-day-to-expiry (0DTE) speculative contracts.
• Upfront Premiums and Margin Norms: Strict mandates enforcing upfront collection of option premiums and the removal of calendar spread margin benefits on expiry days.
• Higher Taxation: Steeper Securities Transaction Tax (STT) levies on futures and options trades, raising transaction hurdles for high-turnover intraday traders.

Impact on Brokers and Market Infrastructure

The twin drop in derivative and cash volumes poses operational headwinds for the broader capital market ecosystem. Discount brokerages, which derive an overwhelming share of their active revenue from F&O transaction fees, face margin compression as retail trader churn rises and onboarding slows. Exchange operators NSE and BSE also face pressure on transactional revenue growth as volumes settle into a lower baseline.

For the regulatory authorities, however, the data signals that policy guardrails intended to prevent outsized retail capital erosion in high-risk contracts are delivering the intended de-risking effect across Indian bourses.
